RE: Wait, what happened to my wifi?

[Simon Fogarty]

Yeah it's kind of weird.

I really don't see how they could have done what you report.

 Hidden is normally hidden unless manually setup / configured 

I've never been in a situation where an ssid for a company was hidden  although 
mac address filtering or enterprise  authentication do make things more 
difficult for access.
Not even seeing ssid is extremely  unusual.

If I recall correctly, hidden ESSID WAPs still show up, just without the ESSID 
specified. Right now I just don't recall whether they say "Hidden"
or just some other string, but I believe they still show as a signal that needs 
accounting for, if for no other reason than to discriminate away from its 
channel to a chosen neighboring channel.

RE: Wait, what happened to my wifi?

[Simon Fogarty]

Hi Janina,

That's interesting what you say you've done and do with regard to w3c 

I'd so love you to check out some of my employers web site and web based 
applications 

 I'd be interested to know what you think of the Oracle product 
Oracle Service Cloud,
Or business objects formily crystal reports,

Doesn't matter what I say they ignore the accessibility situation because fancy 
is better than functional.

Hi, Sandie:

All I can say is that anyone who has known me over the years knows how devoted 
a Linux evangelist I've been. Heck, I'm officially a Linux Fellow of the Linux 
Foundation--for real.

Having said that, I want to add that I've found it highly revealing how 
differently different web browsers handle various web pages. I can show you 
sites that only work under Chrome, or that work best under Safari, or best 
under Firefox. The differences are quite astonishing, actually.
So, for professional reasons, as a Working Group Chair in the W3C, I'm likely 
to try to keep a multi OS environment going.

Beyond that I've found there are some things I want to do with music and audio 
that I can't do on Linux, and I'm tired of waiting for the day I can do them 
there.

Still, It's the OS I'm using right now, as I write this email. I'm on an Arch 
Linux tower machine running Speakup in a console with Mutt as my email client. 
While I also have Thunderbird open, and Apple Mail on my laptop, I default to 
mutt unless there's some reason to move to one of the other clients. Usually 
the reason that gets me to move is the need to clink on embedded links in an 
email message.

When it comes to hardware though, I may agree with you. I'm not sure I like the 
idea of no physical function keys, and I certainly don't like the idea of no 
boot chime. That would make using a more modern Apple laptop a real nuisance in 
a triple boot environment. So, much as I like using Safari and several other 
Apple software apps, I'm unlikely to get another Airbook.

Best,

Janina

Janina, i moved from Cph out in the country so right these days I’m all about 
artificial sight , so i dont think i will run into them. I will say hi if i do, 
of course.
What is funny to me is that i might end up running the project on some form of 
Linux, and when i look around in the office, i can see at least 4 mac 
computers, it is interesting to me how stuff runs in circles sometiems.

Hi, Sandie:

Yes, yes, I remember my trips to Copenhagen very well. I was very happy
to share what I knew at the time, and Hans and all the folks at the
Institute were always so very gracious. It's a fond memory for me.

Speaking of music, I see there's a very interesting project with
MusicXML at the Danish Institute. It seems it's all for JAWS right now,
but I'm hoping they have bigger plans. I don't have all the details, but
I think they're on a very good path.

BTW: If you run into Hans and Mitsy, please say Hello from me. I've been
thinking of them recently and hope they're doing well.

Best,

Re: Wait, what happened to my wifi?

[Sandie Jazmin Kruse]

Janina, agree i run my artificial sight on some Linux stuff, the thing is 
amazing... but what is best, on Linux you can submit, torture,whip the system 
into exactly what you want it to be.
Something i had to the first time i took my setup riding on horseback...
That is a story far from this list though.
I remember clearly when you was in Denmark talking about Linux Hans Rasmussen 
was all over me months after to find out what i used, and, what is as 
important, how.
I am glad most blind people have learned to use apple, now we just have to 
teach them how to use android.
As for music, with you on that , Linux socks, i would love to have my Keytar 
module on Linux, but it is on mac, so i can live with that .

I'm happy to tell you there are lots of gluten free options here in the
States for folks, at least in the larger metropolitan areas. And, we had
gluten free options at the catered lunch buffet at our Southampton
meeting.

I just happen to be an omnivour.

Yes, I'm thinking Apple should be made aware, but not sure how to go
about it. Maybe I simply need to phone their tech support and say so.

Well, possible--but that doesn't explain why all the available ESSIDs
were so visible under Linux and under Windows on the very same machine.

I should add that my hotel wifi came up once, but only once under
Mojave. I tried it first and got no signal. I booted to Windows and
connected immediately. I rebooted to Mojave and got signal. But, I never
saw it again at the hotel under Mojave, not even once.


Under Windows and Linux I never failed to see all the several ESSID
options, there were about half a dozen, available at the University.

Re: Wait, what happened to my wifi?

['Janina Sajka' via MacVisionaries]

If I recall correctly, hidden ESSID WAPs still show up, just without the
ESSID specified. Right now I just don't recall whether they say "Hidden"
or just some other string, but I believe they still show as a signal
that needs accounting for, if for no other reason than to discriminate
away from its channel to a chosen neighboring channel.

Janina, let this be proof to you that Linux, always ... not just sometimes but 
always works... 
i have i believe in public so i cant even run from it said “Linux is cute”
And one thing is sure, next computer is not going to be a Apple product.
Ive had the same issue when going to England, it is not acceptable. Going to 
the us everything works cutely as one would expect.

RE: Wait, what happened to my wifi?

[Simon Fogarty]

Not really something people do.

 Hiding the ssid would be something but a different software shouldn't hide the 
ssid or change the frequency of the network signal.

 The signal would be still in the 2400 or 5G range for the device to see.

Connectivity is a different situation again.

It would be a possibility were there a radio signal to attach to, but there 
isn't. The only way this could be possible is if they were using a nonstandard 
radio frequency for which the Apple hardware isn't tuned.
I'm not even sure you could retune via software alone. Maybe.

RE: Wait, what happened to my wifi?

[Simon Fogarty]

Hi Janina,

I think I'm going to struggle if I travel over there.

 Being gluten free due to health reasons it's bad enough here in NZ to get 
proper gluten free food.

 Soupwith cheese sounds dangerous.


I'm interested in the no SSID situation,

 Could they simply have their SSID's hidden and not realise what they are doing?
And if their networ is so restricted it might be something they do to restrict 
access even further than normal.

Would be worth looking at just to have a play.

Thanks, Simon. No ESSIDs when booted to Mojave. Lots of ESSIDs on Windows and 
Linux.

I don't mind telling you it made me real glad I had Windows and Linux on this 
machine. I was there to work.


And, just to close the loop, the University was putting some strange 
restrictions on the login process. Even their staff couldn't successfully log 
me in on Windows. We had to send my mac address to the University's IT 
department to have me entered as an allowed exception in their firewall tables 
before I actually got access.

That's not the first time I've had unusual difficulties in the U.K. I remember 
a JTC1 Special Working Group on Accessibility meeting some years ago, probably 
a decade or so, that was hosted in London at the British Standards Institute 
(BSI). That place was so locked down they only allowed you out on port 80, i.e. 
all you could do with your computer is surf the web.

Well, I raised a stink. I rely on ssh access to my data center hosted server. 
They took my mac address and gave me port 22 for the duration.


Then there are the various hotel wifi systems around the planet, not so 
restricted these days as they were when wifi was first introduced in hotels. 
TOS agreements seem mostly gone now, thankfully. I never understood that. Could 
you imagine having to sign a TOS to use the electricity? What's the diff?

Anyone, perhaps the funniest part of wifi use in foreign hotels is getting the 
password and login data entered correctly. They want to give you a piece of 
paper, of course. Well, OK, they will be gracious and try to help you in 
person, but it really needs to be in person usually, and not over the phone, 
because they don't usually know the alphabetic character names in English. I've 
had them in my room with the laptop on the desk point my finger to the correct 
key. Example: the letter y was not something my sighted assistant in Malaga 
knew how to say in English!


Almost as bad as going through the buffet line with someone who's English 
doesn't usually extend to brockley and stuffed cabbage.

Even though I've digressed, I will add one last thing ... On my way out of the 
country to England I was early to Dulles Airport and was graciously comp'd a 
pass to the British Airways Business Lounge. Lovely.
I enjoyed waiting there. And, I got personal service. The immigrant who waited 
on me tried to be very helpful, but we had to negotiate language difficulty to 
do so, e.g. I was offered "Brooklyn Soup." When I asked what was in it I was 
told "cheese." Cool, I tried it. Turned out to be "Brockley and Cheddar Soup."

Best,

Janina

Hi, Georgina:

I had a cable with me, but the hotel didn't have an rJ45 jack handy, and
none seemed available in the room at the University where our meeting
was conducted.  I wouldn't have expected any issues, though. I believe
that's a different chip.

Hello Janina,

Oh, I see, I didn’t realise that you were not even seeing any SSID. 
Incidentally did ethernet connection work?

Re: Wait, what happened to my wifi?

['Janina Sajka' via MacVisionaries]

Thanks, Simon. No ESSIDs when booted to Mojave. Lots of ESSIDs on
Windows and Linux.

I don't mind telling you it made me real glad I had Windows and Linux on
this machine. I was there to work.


And, just to close the loop, the University was putting some strange
restrictions on the login process. Even their staff couldn't
successfully log me in on Windows. We had to send my mac address to the
University's IT department to have me entered as an allowed exception in
their firewall tables before I actually got access.

That's not the first time I've had unusual difficulties in the U.K. I
remember a JTC1 Special Working Group on Accessibility meeting some
years ago, probably a decade or so, that was hosted in London at the
British Standards Institute (BSI). That place was so locked down they
only allowed you out on port 80, i.e. all you could do with your
computer is surf the web.

Well, I raised a stink. I rely on ssh access to my data center hosted
server. They took my mac address and gave me port 22 for the duration.


Then there are the various hotel wifi systems around the planet, not so
restricted these days as they were when wifi was first introduced in
hotels. TOS agreements seem mostly gone now, thankfully. I never
understood that. Could you imagine having to sign a TOS to use the
electricity? What's the diff?

Anyone, perhaps the funniest part of wifi use in foreign hotels is
getting the password and login data entered correctly. They want to give
you a piece of paper, of course. Well, OK, they will be gracious and try
to help you in person, but it really needs to be in person usually, and
not over the phone, because they don't usually know the alphabetic
character names in English. I've had them in my room with the laptop on
the desk point my finger to the correct key. Example: the letter y was
not something my sighted assistant in Malaga knew how to say in English!


Almost as bad as going through the buffet line with someone who's
English doesn't usually extend to brockley and stuffed cabbage.

Even though I've digressed, I will add one last thing ... On my way out
of the country to England I was early to Dulles Airport and was
graciously comp'd a pass to the British Airways Business Lounge. Lovely.
I enjoyed waiting there. And, I got personal service. The immigrant who
waited on me tried to be very helpful, but we had to negotiate language
difficulty to do so, e.g. I was offered "Brooklyn Soup." When I asked
what was in it I was told "cheese." Cool, I tried it. Turned out to be
"Brockley and Cheddar Soup."

Best,

Janina

Re: Wait, what happened to my wifi?

['Janina Sajka' via MacVisionaries]

It would be a possibility were there a radio signal to attach to, but
there isn't. The only way this could be possible is if they were using a
nonstandard radio frequency for which the Apple hardware isn't tuned.
I'm not even sure you could retune via software alone. Maybe.

Re: Wait, what happened to my wifi?

['Janina Sajka' via MacVisionaries]

Gina,

You're asking about the next level of configuration when asking about
static or dynamic. That's the configuration of the IP address, the
netmask, the identification of the gateway, and of name resolving
servers, i.e. dns.

I'm not getting far enough for those questions to even come up. For the
record I'm set for dhcp, but it's not yet relevant. Here's why:

When I press VO+m+m and arrow to the wifi menu, there are no access
points listed to choose among. None. Zip. Nada. There's a message in
that menu that says "no signal." 

If I go under System Preferences and then Networking I can eventually
move myself to a set of tabs, one of which is 802.1x. There's nothing
special there. It's all default Apple configuration. But, the machine
isn't seeing anyone to talk to.

Same hardware, same electricity, different results between OS X that
ain't working, and Windows and Linux that are.


This is an analog issue of some kind. It's about establishing a radio
link. Until a radio link is proferred, nobody's login or permissions
pol.icies can possibly apply.

Best,

Janina

RE: Wait, what happened to my wifi?

Hi Janina,

I knew that I was just being stupido,

 Just wondering if you could actually see the ssid's for the UK based networks 
or if you just had nothing?

I'm assuming you don't have static ip setup on the mac side?

Hi, Simon:

I mean the wifi radio in my early 2014 era Mac Airbook didn't work in the U.K. 
when booted to Mojave. It worked perfectly well when booted to Windows 10 or 
Linux. And, it's been working perfectly in Mojave since I came home to the U.S.

That's the weird part and suggests some kind of driver flaw to me.
That's my best guess, anyway, because it's the only thing that's different?

Re: Wait, what happened to my wifi?

[Georgina Joyce]

Hello,

Not really, some parts of university access can be strictly controlled. 
Although, if the admins gave log-in details they would have specified 
prerequisites. This doesn’t explain why Windows and linux work but OSX doesn’t. 
True for MAC address identifiers too.

It has to be something in the OSX configuration. If my understanding is 
correct. Constants are the Uni network, Janina’s hardware and the difference is 
the OS that Janina is using with that hardware. Perhaps, different DHCP 
configuration or implementation. Janina, is it static or dynamic config? Does 
OSxX have a network log? Look at the logs and see what is reported. Oh those 
days of command line hacking!

Kind regards,

Gena

Re: Wait, what happened to my wifi?

['Janina Sajka' via MacVisionaries]

Hi, Gina:

As Simon said, I hadn't been there before, even though I confess to
being bad from time to time! 

Also, I can expand that I had the same problem in the hotel, which was
about a mile off campus.

Re: Wait, what happened to my wifi?

['Janina Sajka' via MacVisionaries]

Hi, Jonathan:

Yes, I tried searching online for 
+wifi +"no signal"

But that yields so many, many results that are far more prosaic. In the
time I spent looking at those results, I didn't find anything that
actually seemed pertinent.

Re: Wait, what happened to my wifi?

['Janina Sajka' via MacVisionaries]

Hi, Simon:

I mean the wifi radio in my early 2014 era Mac Airbook didn't work in
the U.K. when booted to Mojave. It worked perfectly well when booted to
Windows 10 or Linux. And, it's been working perfectly in Mojave since I
came home to the U.S.

That's the weird part and suggests some kind of driver flaw to me.
That's my best guess, anyway, because it's the only thing that's
different?

RE: Wait, what happened to my wifi?

[Simon Fogarty]

Hi Janina,

I'm kind of confused,
Do you mean your USA based WiFi was working for you in the UK on linux but not 
on Mac OS?

Subject: Wait, what happened to my wifi?

Hi, I'm befuddled by losing wifi while in the south of England this last week. 
Thankfully, I had a Bootcamp hosted Windows 10 available which was able to use 
wifi.

What could the the explanation possibly be? And, more importantly, what's the 
fix? I expect to travel again with my Airbook, and I certainly can't accept 
having wifi access be a crapshoot.

Let me be clear:

1.) Wifi has been working perfectly at home and on the go in the
States. I should note I'm fully updated with Mojave.

2.) I travel to the University of Southampton in the U.K., and I get "no 
signal." But,
if I boot to Windows or to Linux, I have wifi.

3.) I return home to the States, and wifi is working again in Mojave.

All thoughts on this conundrum most welcome.

Janina

Hello,

Weird idea, are there any blacklists applied? On your side or the University?

Sorry, I can’t look up WiFi standards right here and now, but I believe that UK

primarily RJ45 connectors, so I have no direct experience. Perhaps if you had

Re: Wait, what happened to my wifi?

['Janina Sajka' via MacVisionaries]

Thanks, Tim, but my problem wasn't an inability to connect to some
domain. That's a logical issue with TCP/IP, so a step further down the
road. I wasn't getting far enough to have an IP address from a local
access point, let alone a fully established connection to a gateway
where DNS whould start to matter.

My problem was more fundamental. The wifi radio just wasn't seeing any
available access points. It was detecting no 802.11 radio signal, while
Windows and Linux had no problem with the self-same hardware. It's
possible it's some kind of channel scanning issue on either the 2.4 or 5
GHz bands, so something with the current driver.

Maybe I should take the question to some mainstream Mac forum, but I'm
not sure where that might be. This list is my go to source for all
things Mac.
